In a cold climate water gets frozen causing damage to radiator of a car. Ethylene glycol is used as an anifreezing agent. Calculate the amount of ethylene glycol to be added to `4 kg` of water to prevent it from freezing at `-6^(@)` . (`K_(f)` for water = `1.85 kg mol^(-1)`)

Text Solution

Verified by Experts

Given,
`DeltaT=6^(@)C,W=4kg=4000g,m=62,K_(f)=1.85`
`w=(mxxWxxDeltaT)/(1000-K_(f))`
`=(62xx4000xx6)/(1000xx1.85)=804.32g`.
